This shaft F is held by thespring F3 yieldingly toward the end of the shaft D5, but its motion islimited by the engagement of the collar F withv the bracket F1 so thatthere is a distinct clearance between the end of the shaft D5 and thebumper head F2 when the parts are in the vnormal working position.

lt will be evident that while we have shown in our drawings an operativedevice, still many changes might be made both in size, shape andarrangement of parts without departing materially trom the spirit or ourinvention and we wish, therefore, that our drawings be regarded as in asense diagrammatic.

The use and operation of our invention are as ollows:- i

A car to be dumped is run upon the dumping cradle. The operator places`the bumpers by operating machinery in any' suitable manner so that theabutments are in the path of the car wheelsr and the car wheels come incontact with them. This forces the bumper members forward compressingthe springs and making the cradle carry a part of the load. Longr beforethe s rings on the cradle have reached the end all their excursion theshaft carrying the o umpcr engages a shaft on the fined abutment andheavier springs on the fixed abutment come into operation and stop thecar. As soon as the shock or power of the car has been distributedbothsprings will expand.

lt has a curved surface bumperl Les-Looe again and the lighter spring onthe cradle will force the car back a short distance until each of theshafts on the cradle has disen, .ged from the bumper head on the sharilso that there will be no danger of any parts interlocking to preventrotation of the cradle.

lt will be understood, therefore, that these two sets of springsoperating successively distribute the shock of stopping the car andreduce the blow upon the cradle itself to a point where no danger needbe anticipated from that. source. forces the parts bacia. into thenormal position and the car is held by this spring after it has come torest. The parts are free and there is no possible interference of therotary movement of the cradle.v
